EN 462-1:1994-ISO19232 Wire Type were introduced as a EUROPEAN STANDARD to supersede the German Standards Institute (DIN 54.109) and the British Standards Institute (BS3971:1980 type 1) Image Quality Indicators. Each indicator consists of a series of seven parallel wires of different thicknesses mounted and encapsulated between two thin sheets of transparent, flexible PVC. A lead mongram indicates the number of the thickest wire, the material and the EN symbol.

Indicator Sizes:
There are four sizes of EN-ISO Image Quality Indicators.
Size 1- contains wire numbers 1 to 7 and used for material thicknesses in the range of 40 to 160mm
Size 6 - contains wire numbers 6 to 12 and used for material thicknesses in the range of 12.5 to 50mm
Size 10 - contains wire numbers 10 to 16 and used for material thicknesses in the range of 5 to 20mm
Size 13 - contains wire numbers 13 to 19 and used for material thicknesses in the range 2.5 to 10mm

All sizes are available in Steel (Fe), Aluminium (Al), and Copper (Cu) Titanium (Ti) Image Quality Indicators are only available in sizes 10 and 13.
As an illustration the identification (i.e. lead monogram) for, say Size 1 (Wire numbers 1 to 7) in steel (Fe) would be 1 FE EN
All EN-ISO Image Quality Indicators are individually numbered and supplied with a Certificate of Conformity, with or without wallets. (Please specify)

Image Quality Indicators with the letters EN are considered to be identical to Image Quality Indicators with letters ISO.

Fidgeon Ltd will continue to supply these Image Quality Indicators with he letters EN and not ISO with Certification to meet EN & ISO specifications
